CARL P. BARBY, OF SHEYENNE, NORTH DAKOTA.

APPARATUS FOR SHIELIDING VEHICLES FROM DUST.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed May22, 1907, Serial No. 375,155.

T all whom it may concern:

Be it known that I, CARL P. BARBY, a citizen of the United States, residing at Shey-' enne, in the county of Eddy and State of North Dakota, have invented certain new and usefulIm rovements in Apparatus for Shielding Vehicles from Dust, of which the following is a specification.

This invention relates to dust guards for road vehicles and more'particularly to mechanical guards of this kind, and has for its object to provide a guard which will be arranged for operation to exclude dust from certain ortions of the vehicle to which it is attache The present guard is especially designed for use on traction on ines to exclude dust from the machinery and the operator thereof.

Various objects and advanta es will be apparent from the following speci cation and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims, without de arting from the spirit of the invention.

11 the drawin s forming a portion of this specification an in" which like numerals of reference indicate similar parts in the several views; Figure 1 is a side elevation of a traction engine provided with the present invention; Fig. 2 1s a front view; Fig. 3 is a vertical section through the casings on line 33 of 2. Fig. i is a top plan; Fig. 5 is, a detail view.

Referring now to the drawings, there is shown a traction engine 6, upon the boiler 7 of which is mounted an upwardly extending bracket 8, including spaced attaching legs 9 and a connection member 10. In the top member, there is mounted a vertical bearing block 11, in which there is journaled a vertical shaft 12, seated at its lower end in a foot piece 13 mounted upon the boiler 7 between the legs 9 of the bracket, and this shaft carries a pulley 14 adjacent to its lower end, for the reception of a driving belt 15.

Mounted upon the bracket 8 there is a late 8 to which there is secured a casing 16 mcluding upper and lower drum sections 17 and 18 respectively connected by means of a horizontal disk 19 secured therebetween. The lower section 18 has an o ening 18 in its bottom at the center thereo across which the plate 8 extends, the. latter having air inlet openings 8" therein.

In the top 17 of the section 17, there is formed an air inlet opening 17 which is section and having a bearing block 20 mounted therein in which the shaft 12 is journaled. Mounted u on the shaft 12 within each drum section 0 the casing there is a fan 21, revoluble with the shaft, and these fans are arranged to draw air currents inwardly through the air inlets of the drum sec tions.

Each fan 21 consists of two arms 22 which spanned by a bridge piece 20 secured to the i are formed by placing rods 23 at o posite sides of the shaft 12, these rods exten ing oppositely beyond the shaft and having attac' ing bolts 24 engaged therein and in the shaft. Wings 25 are secured between the rods at. the outer ortions thereof, as shown. Each fan 21 inc udes also a pair of arms 26, each of which is formed of a pair of parallel rods 26, secured at their inner ends to the rods'23 at the centers thereof, the rods 26 having their inner portions bent outwardly to rest against the rods 23 for the engagement of attaching devices therethrough. Wings 27 are secured between each pair of rods 26 at the outer portions thereof.

A pair the upper drum section 17 of the casing, at opposite sides thereof, and ,extend downwardly, in position to discharge air currents against the dust arising from the front wheels of the engine, to drive the latter outwardly. Air pipes 29 similar to the pipes 28 communicat e with the lower section 18, and are directed downwardly and rearwardly, to further deflect the dust, and these pipes 29 have deflector lates 30 located at their outer ends to suitab y direct the air currents. These deflector plates are tapered toward their inner ends, which ends are secured within the pipps 29 by means of rods 31, as shown.

shaft 12 above the casing 16, and has a set screw therein arranged for operation to impinge against the shaft to hold the fan at diflerent points of its movement and to hold it against rotation upon the shaft. is thus arranged for adjustment upon the shaft, and this fanis located to agitate the air above the section 17, and to carry the dust to the sides of the machine; which action of the fan-will partly prevent the in-- gross of dust to the section 17.

What is claimed is:

1v In an apparatus of the class described,

of air pipes 28 communicate with fan 32 is slidably mounted upon the I This fan the shaft Within the drum sections, air discharge pipes communicating with the drum' sections, and a fan carried by the shaft above the casing.

2. In an apparatus of the character described, the combination with means for generating air currents including a casing having an inlet opening therein, of a fan arranged to agitate the air above the casing.

3. In an apparatus of the class described, the combination with a casing having an air inlet opening, of a revoluble shaft located in said opening and'extending outwardly of the casing, a fan carried by the shaft within the casing and afan adjustably mounted upon the shaft outwardly of the casing.

4. In an apparatus of the class described,

the combination with an air plpe of tapered deflector plates disposed with their minor ends within the pipe and with the major ends outwardly thereof, and rods connected with the pipe and with the minor ends of the deflector pipes.

In testimony whereof he affixes his signature, in presence of two witnesses.

CARL P. BARBY.
